Why in the world would you want to abbreviate that, yulsie?
(To answer your question, no; it's pretty standardly said straight out.)
In relation, however: TTT. I don't see it much here, but it is on other certain boards a lot and you may run across it. It stands for Third Tier Toilet (or various other things) and is basically used to say 'my school is better than yours,' as in (from urbandictionary.com) "UC Berkeley is a TTT. MIT all the way!"
